Cloud Posted June 16, 2016 Share Posted June 16, 2016 So, about 3-4 weeks i faceplanted when my wheel gave in after i tried to accelerate on a low battery. I thought i was more or less ok, and i dint really have issues except bruises, but a couple of weeks ago I noticed that my knee started to swell up - apparently its either blood accumulated inside or this liquid that i dont remember what its called. See attached pics - you can see the difference between the two knees. I did an xray yesterday and im waiting for the results, not sure bow serious it is. the point of my post is - wear the freaking knee protection!!!!! I find that, at least for me, it is the most vulnerable spot on the body when i faceplant Link to comment Share on other sites More sharing options...
Jrkline "Wheel Whisperer" Posted June 16, 2016 Share Posted June 16, 2016 Which wheel were you on? Link to comment Share on other sites More sharing options...

But the battery was probably at 20-25% and althought the speed was not that high, i think i accelerated and that probably caused the wheel to dive or cut off Link to comment Share on other sites More sharing options...
Hunka Hunka Burning Love Posted June 16, 2016 Share Posted June 16, 2016 Oh no! Where's Rehab1? I Googled this: "Knee effusion The rapidity of onset of knee effusion may corroborate a particular diagnosis. Effusion onset within 6 hours supports the assumption of a cruciate ligament tear, articular fracture, or knee dislocation, whereas delayed edema occurs with meniscal injuries. Nearly one half of patients with an acute ligament rupture have localized edema at the site of injury. Complete ligamentous or capsular disruption can give rise to less-than-anticipated swelling if fluid exudes through the tear. Recurrent knee effusion after activity is consistent with a meniscal injury. Localized distension may originate from bursitis (prepatellar bursitis), meniscal cystic changes, outgrowth of a popliteal cyst (Baker cyst), or dilation of an artery (popliteal-artery aneurysm)." http://www.webmd.com/a-to-z-guides/meniscus-tear-topic-overview I think EUC makers should think about implementing a small 4-6 cell battery pack that is held in reserve from the main packs to act as a sort of "Burst Mode" or "Emergency Reserve" power source that can kick in if the main cells are over-taxed in situations where the main reserve power is running low, over-leans, uphill situations, etc. Link to comment Share on other sites More sharing options...

(e.g. 680 Wh, 340 Wh) Was it the 800w motor version? I think in general everyone should be very careful and ride less aggressively once the battery is less than "half full". Especially the lower the amount of parallel battery packs the wheel has since that would increase the "voltage drop" problem. For example, 680 Wh has four parallel packs while 340 Wh has two parallel packs. Regardless, I hope your injury is nothing too serious and you recover fast.

Cloud Posted June 16, 2016 Author Share Posted June 16, 2016 840wh. 800w I wasnt riding aggressively, but i should have acelerated slower Thanks man, i hope so too Link to comment Share on other sites More sharing options...

who_the Posted June 16, 2016 Share Posted June 16, 2016 OUCH! How is your range of movement? OK I hope. Hopefully the edema will dissipate on its own or can be drained. Head, knees, elbows, wrists; all worth protecting when we ride! I admit I only wear a helmet and serious gloves when I ride, even though I've hurt an elbow in a previous fall (overlean, uphill, IPS Zero).

US69 Posted June 16, 2016 Share Posted June 16, 2016 i would say: bursitis...i had that on my right ellbow...just because of a little knock on it... but thats all....hurts...or can hurt....but after a while the swelling goes away and everything should be good again Link to comment Share on other sites More sharing options...
Rehab1 Posted June 16, 2016 Share Posted June 16, 2016 So sorry to hear about you mishap! Yah you sure hit hard! If your range of motion is ok in flexion and extension and you can bare weight without alot of pain you probably just have synovial fluid built up around the patella from the impact that will need to be drained. Best wishes! Link to comment Share on other sites More sharing options...
Jurgen Posted June 16, 2016 Share Posted June 16, 2016 traumatic bursitis probably, so the Xray will show nothing; just have to get it drained (several times) and you'll be as good as new. You probably were lucky, it's just the knee. The most vulnerable for impact is the face>wrist>elbow>knee Protective gear doesn't protect against torsional accidents, you can still get a full ligament tear, so aggressive riding can come a a price May the Big Rider watch over you on your next trip.

DS Posted June 16, 2016 Share Posted June 16, 2016 Oh no, even the experienced riders as you are doing too fast accelerations No wonder why I also do stupid things from time to time. Have on mind that the Xray will show you only bones problems. I hope you do not have ligament/meniscus ruptures. They would be evident in MRI scan. Get well soon.

Rehab1 Posted June 16, 2016 Share Posted June 16, 2016 @Cloud I think we should all post pictures of our bumps, bruises and post op surgery/ xrays. I do not wear protective gear when riding which is stubborn and stupid on my part! The equipment just seems to take away from the freedom of riding. @EUC Extreme is different. If we ride at his caliber we must wear protection to the max! Ok, let me add a photo to the 'EUC Injury Club'. Kind of like the 'Jaws' movie where they compared scars. I encountered an ATV on the road that was not not paying attention thus forcing me into a ditch. Only a bone contusion and all healed now. Link to comment Share on other sites More sharing options...

I admit I only wear a helmet and serious gloves when I ride, even though I've hurt an elbow in a previous fall (overlean, uphill, IPS Zero). I see to be able to have the full range, except that because if the fluid built up, bending all the way is painful. It appears that maybe it looks a little better today, i think it may be dissipating a but. I usually wear gloves but nothing else. Besides the palms, i hit my knees the most, never hit my head, thank god 3 hours ago, KingSong69 said: i would say: bursitis...i had that on my right ellbow...just because of a little knock on it... but thats all....hurts...or can hurt....but after a while the swelling goes away and everything should be good again Yes , i think so, it looks better today, hooe its going away. 2 hours ago, Rehab1 said: So sorry to hear about you mishap!

Yeah, i am a bit surprised this happened as i had had this level of acceleration before on a low battery. Who knows, maybe the pavement was not perfectly even and a little " wave" in the asphalt added more load to the motor. Its hard to exactly recreate what happened 5 minutes ago, DS said: Oh no, even the experienced riders as you are doing too fast accelerations No wonder why I also do stupid things from time to time.

Yeah, i fell a couple of times on a low battery where the wheel didnt have enough power to hold me upright. For a moment i forgot about the battery level and thats when it happens. Not aggressively riding, but on low battery we need to be extra careful and accelerate very slowly. thank you guys, i have to get better soon, a thought of not being able to ride my wheel in the future is killing me! So i have to get better:) 6 minutes ago, Rehab1 said: @Cloud I think we should all post pictures of our bumps, bruises and post op surgery/ xrays.

Yep, had the MBS cutting in once, batt not fully charged, accelarating almost at max, on minimal downward slope, when I ran into a very small pit...barely managed to jump off. minor things but + + + + = too much drain of the batt I try to avoid riding my IPS T680+ below 55V, and tend to be extra careful below 58V (around 80% cap). So when possible I charge to 100% justbefore riding. Link to comment Share on other sites More sharing options...

As most of us are not medical doctors you should consult some of this gods in white closes to have a look on your knee. So if any one like to talk on safety..

Hunka Hunka Burning Love Posted June 16, 2016 Share Posted June 16, 2016 It might be an idea to get some padded knee protectors with some hard outer shells and Velcro straps. If you wear loose enough pants they might be able to be worn underneath, but then it would be a pain to put on and take off at a destination. It might not help with torsion injuries, but at least it's an added layer of something between hard asphalt and your body. I'm still waiting for my protective pads, jacket (with elbow, back, and shoulder pads), and an extra helmet. When you consider that we are rolling on a single wheel it's quite a balancing act of physics, electronics, and magic so it's easy to take it for granted that we're invincible and forget that we are teetering on a small, single contact patch. Have you ever forgotten to turn the wheel on and tried to get on? I've done that a few times, and you come to realize that there's quite a bit that the electronics are doing for you. The average EUC rider might not do a lot of crazy flips and jumps like BMX riders or motorcyclists, but at the speeds we're going at it's easy to see how high the risk for injuries can be. Unfortunately it can take a serious injury before the protective wear goes on. I've seen so many posts about injuries that I'm thinking yeah I don't want to be in that situation so I'm riding carefully and getting some padding just in case. I like riding my EUC too much to be sidelined for any reason. @Rehab1 - Did you get your Flame Edition NB1E+? Hate to sound like a certain restaurant ad, but I'm lovin' it! The colours are pretty low key but still enough to make it stand out. I rolled by a couple of bicyclists taking a break on a bench, and they both shouted out "That's awesome!!" I gave them a thumbs up as I rolled past. After a while, you almost forget the first time you saw a rider on an EUC so it's nice to be reminded every so often by other people's reactions to it. BTW that's a cute helmet on a very cute little kid! He looks ready for some pod racing! Link to comment Share on other sites More sharing options...
